I only buy juices locally. I don't know why that is, other than I can't rely on other people's reviews and was getting quite tired of getting burned on liquids that others loved and which tasted like what I would assume 2 day old vomit would taste like.
The only problem with that is the limitations of what the shops all carry around me. I live in a pretty large metropolitan area of So Calif so there are tons of shops all around but many of them carry the same old stuff, but I did find a new shop (new to me) that has a house liquid named AwesomeSauce that sort of tastes sort of like maple syrup with a light banana thrown in and maybe some other flavors that I have yet to actually recognize what they are but with it being a house liquid I think that $15 / 13ml is too high.
So, pretty soon I'll just make my own liquid and not have to worry about it anymore. I remember going to sites that offer add-shots (like Starbucks that adds add-shots to drinks if desired) but then reading the reviews you get some folks that say 3 add-shots is necessary with this particular liquid and then 2 posts down somebody says "it's strong enough, don't add any add-shots or you'll be sorry you did". So, absolutely hate shopping online for liquids since I can't try before buying and am SO F'ing done with buying liquids only to find out there not anywhere near good as some people make them out to be.
